12.25 Pan/Tilt Angle Assignment
Pedestal Control Command Type 2
Function
To assign angle (position) in Pan/Tilt direction
Command 0062h
Length 8
byte
Range
Within range of Pan and Tilt movable range
Pan : –889~ +889 (7C87h~8379h)
Default Range
(normal mounting) Tilt : –267~ +267 (7EF5h~810Bh)
Pan : –1511~ +1511 (7A19h~85E7h)
Parameter
Default Range
(inverse mounting) Tilt : –800~ +89 (7CE0h~8059h)
Status None
Reference •Parameter value (1LSB) of both Pan/Tilt is equal to approx. 0.1125 by
converting to angle. (see
12.17
and
12.18
)
•Parameter section (8 byte) splits p0~p3 as Pan (position) section, and p4~p7
as Tilt (position) section.
•The range of each parameter is effective within the range set by
Pan
Movable Range Assignment
(
12.27
) and
Tilt Movable Range Assignment
(
12.28
).
•The right direction of Pan angle (position) is positive at the home position
and the left one is passive. The upper direction of Tilt angle (position) is
positive at the home position and the lower one is passive.
•Assign each parameter with the angle (position) at home position. (home
position is 8000h)
Assigned sample of Pan/tilt angle(position) as below
Pan right 90 degrees
⇒
+90/0.1125
⇒
+800
⇒
+320h
⇒
8000h+320h = 8320h
Tilt lower 30 degrees
⇒
–30/0.1125
⇒
–267
⇒
–10Bh
⇒
8000h–10Bh = 7EF5h
•
Pan/Tilt Stop
command can stop motion by force.
The running speed can be set by
Pan/Tilt Speed Assignment
command.
•By issuing this command, Pan/tilt will be in action simultaneously and Pan
and Tilt flag in action among the running status, set 1 and when Pan/Tilt
motion stop, Pan/Tilt flags in action clear to zero.
Note: After power ON, in case of receipt of this command without executing
Pedestal Initialize 1 & 2
, return mode error and execute
Pedestal
Initialize2.
